Specific embodiment
Below with reference to examples and drawings, technical solution of the present invention is further elaborated.
As shown in Fig. 1~7, this encoder includes: with cam structure
Support base 1 is provided with holding tank 11 on the support base 1, and the both ends of the holding tank 11, which are symmetrically arranged with, to be run through
The side wall of hole 1 and through hole 2 13, the through hole 1 and through hole 2 13 is all provided with waist hole 14, the through hole
Lateral surface upwardly extend as fixed part 15, be provided with intercommunicating pore 16 on the fixed part 15；
Triangular cam 2 is detachably arranged in holding tank 11, and the two sides of triangular cam 2 are respectively arranged with track groove one
21 and track groove 2 22, the triangular cam 2 be provided centrally with connecting hole 23.
Balance mechanism 3, the balance mechanism include balance mechanism 1 and balance mechanism 2 32, and balance mechanism 1 is arranged
In in through hole one, balance mechanism 2 32 is set in through hole 2 13, and balance mechanism includes bottom plate 33, support rod 34 and cross bar
35, the support rod 34 is vertically installed on bottom plate 33, and the cross bar 35 is arranged in parallel with bottom plate 33 and one end and support rod 34
Fixed, the free end of the cross bar 35 is stretched out waist hole 14 and is slided in track groove 1 and track groove 2 22 respectively.
Encoder in the prior art is used as voltage input at work, using magnet induction, then passes through seesaw
Structure is realized in the course of work, is clicked by electromagnet so that the springing of seesaw structure progress up and down reciprocatingly, continues several daily
Ten thousand clicks, contact position can eventually lead to due to contacting for a long time and will appear abrasion even breakdown at click, use coding
The service life of device is shorter；Furthermore it eventually leads to and error occurs, moreover, complicated mechanism makes, the error in transmission process
Constantly accumulation, during encoder constantly works, error is also become larger, accuracy decline.
The present invention devises a kind of encoder cam structure thus, passes through the rotation of triangular cam 2, one 21 He of track groove
Track groove 2 22 also moves therewith, and since the free end of symmetrically arranged balance mechanism two is stretched out from waist hole 14, which exists
It is rotated in track groove 1 and track groove 2 22, so as to carry out the movement of vertical direction along waist hole 14, is finally made
It obtains symmetrically arranged bottom plate 33 and carries out reciprocal upward downward movement: similar seesaw, symmetrically arranged one of bottom plate
33 move upwards, another bottom plate moves gradually downward.When one of bottom plate 33 moves downward, another bottom plate 33 to
Upper movement.
Two symmetrically arranged bottom plates 33 are driven to carry out reciprocal up and down motion using the rotation of triangular cam 21, comparison is existing
There is technology, electromagnet constantly clicks the up and down motion so that bottom plate, and triangular cam 2 drives so that control precision raising, error
Reduce, and can prolonged use, be not in breakdown or breakage situation.
As a further improvement, pair of protrusion 1 and track groove 2 22 is correspondingly arranged in the track groove 1
It includes that semicircle one 212, described raised 2 221 includes semicircle 2 222 that protrusion 2 221, described raised 1, which should be provided with,
The radius length of semicircle one is a, and the radius length of semicircle two is b, meets quantitative relation a <b, wherein semicircle one and half
Circle two is arranged in the two sides mirror symmetry of triangular cam 2.
It is arranged so that under the driving of triangular cam 2, two symmetrically arranged bottom plates 33 are able to carry out reciprocal fortune
It is dynamic, it is ensured that encoder can be operated effectively for a long time, and precision improves.
As a further improvement, the width of the track groove 1 and track groove 2 22 and cross bar diameter matches.So
Setting, in triangular cam rotation, the free end of cross bar can be slided in track groove 1 and track groove 2 22.
As a further improvement, the two sides of the through hole 1 and through hole 2 13 are all symmetrically arranged with threaded hole 4.
The setting of triangular cam 2 can need the up and down motion of the work to bottom plate 22 to control according to real work, make
With convenience, the precision of encoder is improved, it is applied widely.
As a further improvement, the side wall of the triangular cam 2 is provided with several fixation holes.When specifically used
It waits, is inserted into fixing piece in fixation hole 24, the connecting hole 23 of triangular cam 2 can be fixedly installed perforative connecting rod, pass through fixation
Part realizes the fixation of connecting rod and triangular cam 2, furthermore, the other end of connector is connected with driving motor, and then drives triangle
Cam 2 is rotated along axle center.
This encoder is reasonable with cam structure structure setting, triangular cam can be driven to carry out along axis by stepper motor
Heart rotary motion, by the free end of transverse slat track groove 21 and track groove 2 22 sliding, so that two bottom plates 22 be driven to carry out
Upper and lower seesaw movement, work efficiency is high, and precision improves；During specifically used, injection lubrication can according to need
Oil, whole wearability improve, and station position is accurate, and noise is also small, and service life can achieve 10 years or more.
Described herein is only the preferred embodiment of the present invention, but protection scope of the present invention is not limited to
This.The similar side of the modify or supplement or adopt that those skilled in the art in the invention carry out described specific embodiment
Formula replacement, should all be covered by within protection scope of the present invention.
